Abstract: <P>PROBLEM TO BE SOLVED: To suppress temperature variations of oil in a pan depending on the amount of curvature of the bottom of the pan by precisely detecting the amount of curvature of the bottom of the pan appropriate to the temperature of the pan at the start of heating.  <P>SOLUTION: When the temperature θs at the start of energization of a heating means 3 is lower than 70 °C, an energization control means 17 detects the amount of curvature of the bottom of the pan based on the gradient of a temperature rise under the energization of the heating means 3, thereby temperature controlling temperatures in accordance with the amount of curvature of the bottom of the pan while preventing the extension of a preheating time due to the interruption of the energization of the heating means 3. When the temperature θs is 70 °C or higher, the control means 17 interrupts the energization after the heating means 3 is supplied with only predetermined integrated power, and detects the amount of curvature of the bottom of the pan based on the degree of temperature rise/fall thereafter. The amount of curvature of the bottom of the pan is thus detected with relatively small integrated power, and an excessive rise in the temperature of oil in a pan with a curved bottom is thereby prevented.  <P>COPYRIGHT: (C)2004,JPO
